His name and date of birth have also been redacted on the death certificate, but editors at the website report it does belong to Avicii.

Avicii’s family previously suggested the late DJ was trying to find “peace” before his death, but have not released any details surrounding his passing.

“Our beloved Tim was a seeker, a fragile artistic soul searching for answers to existential questions,” a statement read. “An over-achieving perfectionist who travelled and worked hard at a pace that led to extreme stress. When he stopped touring, he wanted to find a balance in life to be happy and be able to do what he loved most – music. He really struggled with thoughts about Meaning, Life, Happiness”.

“He could not go on any longer,” the statement continued. “He wanted to find peace. Tim was not made for the business machine he found himself in; he was a sensitive guy who loved his fans but shunned the spotlight…”.

According to reports, Bergling suffered from health issues related to excessive drinking, and had his gall bladder and appendix removed in 2014.
